曰∶
大贝出日南，如酒杯；小贝，贝齿也。善治毒，俱有紫色是也。洁白如鱼齿，故一名贝齿。
古

珂亦似此而大，黄黑色，其骨白，可以饰马。

味咸，性平，有毒。主治目生翳膜、鬼疰（一种传染性痨病）、蛊毒、腹痛下血、五癃（五种小便不通的病症），能通利水道，消除寒热温疰，解肌表之邪，散结聚之热。烧制后使用效果更佳。又名贝齿。产于东海的池塘沼泽中。
陶隐居说：这是现在小小的贝子，人们用来装饰军容和服饰用品的，出产于南海。将其烧成细末，吹入眼中，治疗翳膜效果很好。另外，真正的马珂（即玳瑁）捣碎成末，也能治疗盲翳。臣禹锡等人谨按《蜀本图经》记载：属于蜗牛类，形状像鱼，牙齿洁白的品质好。《药性论》记载：贝子，作为使药使用。能破除五淋，通利小便，治疗伤寒引起的狂热。日华子说：贝齿，性凉。治疗翳障以及鬼毒、鬼气、下血。又名白贝。
《图经》记载：贝子，产于东海的池塘沼泽中，现在南海也有出产。是贝类中最小的，形状又像蜗牛。而《交州记》说：大贝出产于日南，形状像酒杯；小贝就是贝齿。善于治疗毒症，都有紫色。洁白如鱼牙，所以又名贝齿。古人用来装饰军容和服饰用品，现在很少使用，只是穿起来给小孩子玩耍。有的家庭用来装饰镜带，画家有时也用来压物。采集没有固定时间。珂（玳瑁）也类似但较大，呈黄黑色，其骨骼为白色，可以用来装饰马匹。
《海药本草》记载：云南极多，用作钱币货币交换。主治水气浮肿以及小儿疳蚀（小儿疳积导致的腐蚀症状）、吐乳。都经过烧制后入药使用。雷公说：凡是使用，不要用花虫壳，因为两者的味道相似，只是使用无效。凡是使用，先用苦酒（醋）与蜂蜜相对称重，两味混合后，将贝齿在酒、蜜中蒸制，取出，再在清酒中淘洗干净，研磨使用。《圣惠方》治疗射罔混在肉类中的毒性以及漏脯毒。用贝子末，用水调服半钱，有效。或者食用面食中毒，也同样使用。《千金方》点治小儿黑花眼翳，涩痛。用贝齿一两烧成灰，研磨如面粉状，加入少许龙脑（冰片），点眼效果奇妙。又一方：去除目翳。贝子十枚，烧成灰细筛，取一颗胡豆大小的量，放在翳上，躺卧如同煮一石米的时间那么久，翳就会消失。如果是息肉，加珍珠与贝子等分。孙真人治疗食物中毒。取贝子一枚，含在口中，自然呕吐。
《衍义》说：贝子，现在称为贝齿，也像紫贝，但长度一寸多，所以叫贝子。颜色微白，有深紫黑色的，治疗目中翳膜，烧制后使用。北方人用它装饰毡帽以及缀在衣服上，或者做成蹀躞（古代腰带上的饰物）下垂。
Beizi (Concha Arcae)
Salty in flavor, neutral in nature, and toxic. It primarily treats leukoma (opacification of the cornea), Guizhu (a type of infectious tuberculosis-like disease), Guduh (poison caused by gu magic), abdominal pain with bloody stool, Wulong (five types of urinary retention), promotes urination, eliminates chills and fever associated with Wendu (warm malarial fevers), releases the muscle layer, and dissipates clustered heat. It is best used after calcination. Also known as Beichi. It is produced in the ponds and marshes of the East Sea.
Tao Hongjing stated: This refers to the small shells currently used by people to decorate military uniforms and other items, which are produced in the South Sea. When calcined into a fine powder and blown into the eyes, it effectively treats leukoma. Additionally, true Dai Mao (Hawksbill Turtle Shell) crushed into powder can also treat blindness due to leukoma. Ministers Yuxi and others noted according to the *Shu Ben Tu Jing*: It belongs to the snail family, resembles fish in shape, and those with white teeth are of good quality. The *Yao Xing Lun* records: Beizi acts as an envoy drug. It can break up Wulin (five types of strangury), promote urination, and treat hyperthermia caused by Shanghan (cold damage). Rihua Zi stated: Beichi is cooling. It treats leukoma barriers, Guduh, Guiqi (ghost qi), and bloody stool. It is also known as Baibei.
The *Tu Jing* records: Beizi is produced in the ponds and marshes of the East Sea, and is now also found in the South Sea. It is the smallest of the shellfish, resembling a snail in shape. However, the *Jiaozhou Ji* states: Large Beizi is produced in Rinan, shaped like a wine cup; small Beizi is Beichi. It is effective in treating toxins, all possessing purple hues. They are white and clean like fish teeth, hence the name Beichi. Ancient people used them to decorate military uniforms and clothing; nowadays they are rarely used, except for threading them for children's play. Some households use them to decorate mirror straps, and painters sometimes use them to press materials. There is no fixed time for collection. Ke (Dai Mao/Hawksbill) is similar but larger, yellowish-black in color, with white bones that can be used to decorate horses.
The *Hai Yao Ben Cao* records: It is extremely abundant in Yunnan and is used as currency for exchange. It primarily treats edema due to water qi, as well as Ganshi (corrosion caused by pediatric malnutrition syndrome) and vomiting of milk in children. All should be calcined before being added to medicinal preparations. Lei Gong stated: When using, do not use flower insect shells, as their properties are similar but they are ineffective when used. When preparing, first weigh bitter wine (vinegar) and honey equally, mix the two, then steam the Beichi in the wine and honey mixture. Take it out, wash it thoroughly in clear wine, and grind it for use. The *Shenghui Fang* treats toxicity from She Wang (aconite poison) mixed in meat and from Lou Fu Du (poison from dampened bread). Use Beizi powder, mixed with water and taken orally (half qian dose), which is effective. If poisoned by eating noodles, the same method applies. The *Qianjin Fang* treats black flower leukoma in children, causing astringency and pain. Use one liang of Beichi, calcined to ash, ground like flour, add a small amount of Longnao (Borneol), and apply to the eye for excellent results. Another prescription: To remove leukoma. Take ten Beizi, calcine to ash and sift finely, take an amount the size of a broad bean, place it on the leukoma, lie down for the time it takes to cook one shi of rice, and the leukoma will disappear. For pterygium or polyps, add Zhenzhu (Pearl) in equal proportion to Beizi. Sun Simiao treated food poisoning by taking one Beizi, holding it in the mouth, which induces spontaneous vomiting.
The *Yanyi* states: Beizi is now called Beichi, resembling Zi Bei (Purple Conch), but longer than one cun, hence the name Beizi. The color is slightly white, with some being dark purple-black. It treats leukoma in the eyes and is used after calcination. People in the North use it to decorate felt hats, attach to clothes, or make Diexie (pendant ornaments hanging from belts).
